Good durability

Been using this for carbon fiber PLA for two weeks now with no signs of wear. Only giving 4 stars because shipping took a bit longer than expected.

Solid performance

Prints look crisp and detailed. I noticed slightly higher pressure needed compared to brass, but that is normal for hardened steel.

Essential upgrade

If you plan on printing anything abrasive, this is a must-have. The temperature consistency is excellent and clogs are a thing of the past.

No more nozzle erosion

Finally a nozzle that lasts when printing glass-filled nylon. The threading is precise and it seals perfectly against the heat break.

Perfect fit for my A1 mini

Installation was straightforward and the print quality improved immediately. The hardened steel handles abrasive filaments much better than the stock brass nozzle.

5 FAQ

Q: Can this handle pure carbon fiber filament?

A: While hardened steel is much more resistant than brass, pure carbon fiber is extremely abrasive. We recommend it for composites like CF-PLA or CF-PETG, but monitor wear regularly for pure fibers.

Q: Is this nozzle compatible with the original Bambu Lab X1 Carbon?

A: No, this specific assembly is designed exclusively for the A1 and A1 mini series. The X1 series uses a different hotend configuration.

Q: What tools are required for installation?

A: You will need the provided wrench or a standard 7mm socket wrench. Ensure the hotend is heated to about 200°C before removal to prevent damage to the threads.

Q: Does this come with a new silicone sock?

A: No, this package includes only the nozzle assembly. You can reuse your existing silicone sock if it is in good condition or purchase one separately.

Q: Do I need to recalibrate my flow rate after installing this?

A: Yes, it is highly recommended to run a flow rate calibration and potentially re-level the bed after swapping nozzles to ensure optimal print quality.
